You missed tcpControlBits: since it's defined as unsigned16 in [IANA], 
you should either use unsigned16 or explain why unsigned8 is being used 
(eg, say that reduced-size encoding is being used).

Recall:

It would be useful to discuss reduced size encoding and show a specific 
example. eg, if I'm collecting ingressInterface which is nominally a 
u32, but I'm a small device so I only export a u8, should I export:

ingressInterface(10)<unsigned32>[1]

or

ingressInterface(10)<unsigned8>[1]
